Abstract: A method for tile-based rendering of content. Content may be rendered in a memory region organized as multiple tiles. In scenarios in which content is generated in layers, for operations that involve compositing image layers, an order in which portions of the image are processed may be selected to reduce the aggregate number of memory accesses times, which in turn may improve the performance of a computer that uses tile-based rendering. An image may be processed such that operations relating to rendering portions of different layers corresponding to the same tile are performed sequentially. Such processing may be used in a computer with a graphics processing unit that supports tile-based rendering, and may be particularly well suited for computers with a slate form factor. An interface to a graphics processing utility within the computer may provide a flag to allow an application to specify whether operations may be reordered.
